Title: Improvements relating to the dehydrogenation or dehydrocyclisation of non-aromatic hydrocarbons
IPC: C10G35/085
Filed: 1956-11-14
Abstract: A catalyst for aromatizing hydrocarbons comprises 0.01-5% of platinum and 0.01-5% of an alkaline-earth (including magnesium) metal in combined form on a support of alumina and/or silica.  The higher proportions of alkaline-earth metals are used when halogens such as chlorine or fluorine are present, but the catalyst is preferably halogen-free and contains up to 3% of alkaline-earth metal.  The catalysts are prepared by heating a platinum catalyst supported on alumina and/or silica to 150-600 DEG  C., contacting the cooled catalyst with an aqueous solution of a water-soluble salt of the alkaline-earth metal, preferably a fatty acid salt, removing excess solution if necessary, drying at a temperature above 30 DEG  C. and below the roasting temperature and roasting at 200-600 DEG C.ALSO:The aromatization of non-aromatic hydrocarbons containing at least 5 carbon atoms in the molecule is effected by contacting at 300-600 DEG  C. and not more than 50 p.s.i.g. in the absence of added extraneous or recycle hydrogen with a catalyst comprising a minor proportion of platinum (preferably 0.01-5%) deposited on or incorporated in alumina and/or silica and preferably being halogen-free and which may also contain 0.01-5% of an alkaline-earth metal or magnesium in combined form (see Group III).  The process may be applied to the aromatization of specific hydrocarbons, e.g. nhexane or n-heptane, or to the upgrading of petroleum fractions such as a primary flash distillate or a catalytic (e.g. platinum) reformate.  Pressures below atmospheric may be used, but atmospheric pressure is preferred; space velocities of 0.1-1.0 vol./vol./hr. can be used.

Filed: 1947-12-31
Abstract: Aldehydes of the formula CRR1R2-CHR3-CH2-CHO, where R and R1 are ester, amide or nitrile groups (same or different), and R2 and R3 are hydrogen or alkyl, are prepared by treating CHRR1R2 with R3-CH:CH-CHO in the presence of an organic solvent diluent and not more than 0.05 mol. of an alkaline catalyst.  When R and/or R1 is an ester group, the esterifying radical may be alkyl, aryl or aralkyl, e.g. methyl, ethyl, propyl, phenyl, benzyl or tolyl; similar substituents may occur in the amide group.  Specified reactants are ethyl malonate, ethyl monoalkyl-malonates (e.g. methyl, ethyl or propyl), ethyl cyanoacetate, acrolein and crotonaldehyde.  When R and/or R1 is an ester group, this may be converted in the product into an amide or nitrile group.  Examples are given of the preparation of typical aldehydes and their isolation as 2 : 4-dinitrophenylhydrazones. Biotin may be synthesized with the aid of gamma-gamma-dicarbethoxy-butyraldehyde by condensing it with 4-benzamido-3-keto-thiophane to give the 3-(gamma-gamma-dicarbethoxy-butylidene) compound which may be converted into biotin according to known procedures.  In the Specification as open to inspection under Sect. 91, R and/or R1 may be a free carboxylic group.  This subject-matter does not appear in the Specification as accepted.
